Test Drive

Let’s take the latest version of the program for a spin in IDLE. In addition
to turning the sound on and off with the checkbox, you should be able to
dynamically and interactively adjust the volume with the slider.

Flip it on and off.

Turn it way up.

It works. Not only can you
start and stop the track,
but you can now adjust the
volume, too! And all from
the one GUI... sweet!
